Serial Touchscreen Controller(COMBUS) Driver

The Serial Touchscreen Controller(COMBUS) driver enables Windows to communicate with the Egalax serial touchscreen controller and recognize touch input. It is intended for users setting up a compatible touchscreen, reinstalling Windows, or troubleshooting a screen that no longer responds correctly.

Key Features

• Touch input support: Allows a compatible Egalax serial touchscreen to function as an input device in Windows.
• Serial connection support: Provides communication between the operating system and the controller through its serial interface.
• Windows compatibility: Supported operating systems include Windows 10, 8.1, 7, Vista, and XP; select a package that matches your system version and architecture.
• Configuration support: Depending on the package, Egalax utilities may provide calibration and touch settings to help align touches with on-screen controls.

How to Install Serial Touchscreen Controller(COMBUS) Driver

1. Confirm your hardware and Windows version. Check the controller identification in Device Manager or your touchscreen documentation. Verify whether your Windows installation is 32-bit or 64-bit before choosing a driver.
2. Choose a compatible package. For a Serial Touchscreen Controller(COMBUS) driver download for Windows, review the package’s supported devices and operating systems. Select the latest version that explicitly supports your hardware. If comparing Windows 10/11 options, note that Windows 11 support is not confirmed here.
3. Download and prepare the files. Use a trusted source for a free download, and extract the archive if needed. Before replacing an existing driver, consider creating a system restore point.
4. Install the driver. Run the included installer and follow its instructions. If the package has no installer, open Device Manager, locate the controller, select Update driver, and browse to the extracted driver folder. Follow any connection or restart instructions provided with the package.
5. Test the touchscreen. After installation, check whether touches register accurately. Run the supplied calibration utility if available. If the screen remains unresponsive, verify the serial cable connection and consult the device documentation for any required COM port settings.

Keep the driver updated when a compatible release addresses an issue you are experiencing or supports a system change. Before you update, check the release notes and compatibility details rather than assuming the newest package suits every Egalax controller. Retaining a copy of your working driver can make recovery easier if a replacement causes problems.
